• change nmdc-schema's MIxS import to GSC's 6.2 YAML #1368

Hi @pkalita-lbl and @mslarae13

This is a version of nmdc-schema that imports slots form GSC's MIxS 6.2, as opposed to the static, GSC v6.0-like https://github.com/microbiomedata/mixs/blob/main/model/schema/mixs.yaml

I have extensive notes in the accompanying issue #1386 but they may not be crystal clear yet

The thing I want to emphasize here is that I have removed all yq customization of MIxS slots except for the ones that are used in MongoDB as of now. So that means some MIxS slots may be presented to submission-schema now in a slightly different way, so we may need to make minor changes to the sheets_and_friends configuration.

I took a look at the changes here and read through the comments in #1368. I'm not sure I follow every single detail, but that's probably okay. In broad strokes, the goals make sense to me. If there's something you want me to do re: the submission schema before this is merged and/or released, let me know.

Overall, I'm on the same page as @pkalita-lbl . I understand the want and I support it! I think having this static MIxS file is a source of incompatibility and error.
